SERVICE DATA
Service data recorders in your vehicle are
capable of collecting and storing
diagnostic information about your vehicle.
This potentially includes information about
the performance or status of various
systems and modules in the vehicle, such
as engine, throttle, steering or brake
systems. In order to properly diagnose and
service your vehicle, Ford Motor Company
(Ford of Canada in Canada), and service
and repair facilities may access or share
among them vehicle diagnostic
information received through a direct
connection to your vehicle when
diagnosing or servicing your vehicle.
Additionally, Ford Motor Company (Ford
of Canada, in Canada) may, where
permitted by law, use vehicle diagnostic
information for vehicle improvement or
with other information we may have about
you, for example, your contact information,
to offer you products or services that may
interest you. Data may be provided to our
service providers such as part suppliers
that may help diagnose malfunctions, and
who are similarly obligated to protect data.
We retain this data only as long as
necessary to perform these functions or to
comply with law. We may provide
information where required in response to
official requests to law enforcement or
other government authorities or third
parties acting with lawful authority or court
order, and such information may be used
in legal proceedings. For U.S. only (if
equipped), if you choose to use connected
apps and services, you consent that certain
diagnostic information may also be
accessed electronically by Ford Motor
Company and Ford authorized service
facilities, and that the diagnostic
information may be used to provide
services to you, personalizing your
experience, troubleshoot, and to improve
products and services and offer you
products and services that may interest
you, where permitted by law. For Canada
only, for more information, please review
the Ford of Canada privacy policy at
www.ford.ca, including our U.S. data
storage and use of service providers in
other jurisdictions who may be subject to
legal requirements in Canada, the United
States and other countries applicable to
them, for example, lawful requirements to
disclose personal information to
governmental authorities in those
countries.
EVENT DATA
This vehicle is equipped with an event data
recorder. The main purpose of an event
data recorder is to record, in certain crash
or near crash-like situations, such as an
airbag deployment or hitting a road
obstacle; this data will assist in
understanding how a vehicle
’s systems
performed. The event data recorder is
designed to record data related to vehicle
dynamics and safety systems for a short
period of time, typically 30 seconds or less.
The event data recorder in this vehicle is
designed to record such data as:
• How various systems in your vehicle
were operating.
• Whether or not the driver and
passenger seatbelts were
buckled/fastened.
• How far (if at all) the driver was
depressing the accelerator and/or the
brake pedal.
• How fast the vehicle was traveling.
• Where the driver was positioning the
steering wheel.
This data can help provide a better
understanding of the circumstances in
which crashes and injuries occur.
